ROTARY COPYING-MACHIN E.

SPECIFICATION forming part of Letters Patent No. 542,497, dated July 9, 1895. I Application filed April 23, 1894:. Serial No. 508,640. (No model.)

To all whom it may concern:

Be it known that we, GEORGE REHFUSS, JOHN G. REHFUSS, and MARTIN O. REHFUSS, citizens of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Rotary Copying- Machines, which improvement is fully set forth in the following specification and accompany- :0 ing drawings.

Our invention consists of a novel construction of rotary copying-machine, whereby a number of impressions can be readily and quickly reproduced from a single sheet of prepared material, means being provided for adjusting the machine according to requirements, all as will be hereinafter set forth.

Figure 1 represents a side elevation, showing the cover in section, of a rotary copyingmachine embodying our invention. Fig. 2 represents a vertical section of the same on line y y, Fig. 1. Fig. 8 represents a detailed view of the same. Fig. 4 represents an 'end elevation on a reduced scale, showing the de-.

Fig. 8 represents a detail showing the stop detached from the gear. Fig. 9 represents an end elevation of. the 5 movable cam, also detached from the gear. Fig. 10 represents an end elevation of the lower portion of Fig. 6. Fig. 11 represents a front elevation of the frame supporting the inking-rolls in position. Fig. 12 represents a similar view of said frame with therolls journaled therein. Fig. 13 represents a perspective view, on an enlarged scale, of the stop for arresting the motion of the gear-wheel. Fig. 14: represents a side elevation, partially 5 in section, of the revolving arm which carries the sheet of prepared material. Fig. 15 represents an end view of the frame which carries the inking-rolls. Fig.16 represents an Fig. 5 represents a section on Fig. 7

end view of the frame or spider on which the frame carrying the ink-rolls is supported.

Similar letters of reference indicate corresponding parts in the several figures.

Referring to the drawings, A designates the bed of the press, adapted to receive a sheet of paper B, which is shown in dotted lines in Fig. 2 in the act of receiving an impression. O designates an extension of said bed, hinged thereto at D, and E designates a foot for the same, which serves as a support when the extension G is turned down.

F designates feet supporting the bed A.

G designates a casing adapted to inclose the machine when not in use, and H designates a handle hinged to the casing at I. The casing G may be attached to the feet F t 5 at K in any suitable manner when it is desired to transport the press, the extension C being folded up against the casing or housing L, as shown in Fig. 2, said casing L being made in two parts hinged at M. 0

N designates the base of'frames or stand ards suitably secured to each end of the bed A and provided with the arms 0 and P, which terminate in the arc-shaped heads Q and R, which support the housing or casing L. One portion of the said housing L is riveted to the head R, the other half resting on the head Q, so that it can be readily lifted to provide access to the interior. In each of the frames N, at about the junction of the arms 0 and P, is supported the shaft S, which is prevented from rotating therein by the key T or some similar device. The shaft S also carries near each end a frame or spider U, which is pro- I vided with a hub V, said frame being prevented from rotating on the shaft S by means of the set-screws W and having the arms X radiating from the hub V.

In the frames U are journaled the rollers Y, which extend substantially parallel with thev 9o shaft S and with the said frames form a skeleton cylinder whichserves as a support for the prepared paper orother material Z, by means of which the printing is done.

A designates a hub adapted to be revolved 5 on the shaft S, and is supported thereon in the space between the left-hand frames U and N and the arm 0, said hub having the arm B, Fig. 14, which carries the bar which,

as shown in Fig. 1, extends across the press and joins the arm D, which arm projects from the hub or sleeve E, the latter being on the hub F and prevented from turning thereon by means of the set-screws G. The said hub or sleeve F passes through the righthand frame or standard N and is adapted to revolve on the shaft S.

H designates a gear which is integral with the hub F, said gear, therefore, being also adapted to be revolved on the shaft S.

K designates a pinion carried by the shaft T, and is suitably supported below said gear H and adapted at times to mesh therewith, and L designates an arm mounted on the same shaft and carrying a roller X, which is at certain times adapted to engage the cam M on the wheel H.

N designates a feedroller journaled below the bed A and partly occupying the recess 0.

P designates a gear adapted at certain times to mesh with the gear Q, which is secured to the same shaft R as the inking-roll S. The shaft T, which carries the roll N, gears P and K, and arm L, is journaled in the arms U, one arm being located near each end of the roll, as shown in Fig. 1, the other end of the arms U being pivotally secured at V to lugs on the under side of thebed A. W designates springs located adjacent to said arms U, and bearing thereon in such manner that they normally tend to keep the feedroll N in the position shown in Fig. 3, where it is contacting with the paper B, which is receiving the impression from the form or prepared material Z, against which the inkingroll S presses.

Y and Z designate inking-rolls, which are adapted to rotate in hearings in a suitable frame, one end A of which is shown in Figs. 12 and 14, which frame also supports the large inking-roll S. The rolls Y and Z and Y and S are adapted to be in contact with each other, as shown in Fig. 2.

The frame which supports the inking-rolls S, Y, and Z consists of the side portions A and the cross-bar B", said sides A having the lugs or studs C, which enter recesses D in the spider U, the latter having ledges E, which also assist to support said frame, one of said recesses D bein slotted, so that the rolls and the Supporting-frame can be readily removed, as seen in dotted lines in Fig. 11, through the end of the machine.

In the detail shown in Figsxt and 6 B designates a handle by means of which the gearwheel H is rotated, the said gear having on a portion of its exterior face the cam M, adapted at certain times to come in contact with the roller X on the arm or dog L. The

said gear H is faced off, so that it has the annular projection G on which is adapted to slide the slotted arc portion D of the cam, whose working face terminates at 0 said are portion being provided with the projections A which enter the groove F the latter serving as a guide therefor.

The face C of the movable portion D of the cam is held in any desired position by means of the thumb-screw E which works in the groove F in the gear H, whereby said movable part D of the cam can be made fast to the gear at any desired point, whereby the distance between the faces C and M can be varied at will.

G designates a stop attached to the movable arc D which is adapted to abut at certain times against a pin H which is suitably secured to a fiat spring, said spring being riveted at O to a strap L as shown in Figs. 6 and 1 especially.

M designates a push-button, which is connected to the spring K which carries the pin H by means ofthe part N so that a pressure upon the button M will force the spring K inwardly, and also the pin H thus allowing the stop G2 to move on by it, as seen in Fig. 13. The paper Z, from which the impression is taken, is preferably a sheet of paper coated with wax, upon which the matter to be reproduced is imprinted by means of a type-writer or similar apparatus, in the usual 9 way. The paper is then laid over the skeleton cylinder, and one edge of it is ,made secure to the part 0 in any suitable manner, as at 0 Fig. 14.

P designates agage-on the extension-piece O, which can be held in any desired position by means of the thumb-screw Q The ink is applied to the rolls Y and Z. Thence it is evenly distributed upon the inking-roll S.

The operation will now be apparent. sume the parts to be in the positions shown in Fig. 2, the casing Gr being removed, and the hinged extension-piece 0 being let down and on a level with the table A. The pressure of the arc portion D of the cam upon the roller X, carried by the dog L, forces down the arms U, in which is journaled the shaft T, which carries the gears P and K. The paper B is then inserted between the inking-rollers S and the feed-roll N, whose top is about on a line with the top of the bed A, and the gear H is rotated. As the gear revolves in the direction of the arrow the face 0 of the cam D will leave the roller X, whereupon the parts will assume the position shown in Fig. 3, the arms U being forced upwardly by the spring W. The gear or pinion K now meshes with the gear H, and the gear P meshes with the gear Q, causing the rollers S and N to revolve at the same time the prepared paper Z, which is held by the holder 0 and supported upon the skeleton cylinder, is being revolved adjacent to the sheet B, which is pressed against the same by means of the feedroll N. As the paper B passes through the AS-ro5 IIO IIS

rolls the ink will be forced through thecharacters on the prepared sheet Z from the inking-rollerS within, so that the said characters will be clearly and sharply reproduced upon the sheet B. By the time all the characters have been reproduced on the paper the revolution of the gear H will bring the face M of the cam into contact with the roller X and the feed-roller N will be forced down, as in Fig. 2, and a further revolution ofthegear H will bring the stop G upagainst the pin H The sheet B can then be removed and another one substituted. The button M is then pushed in, allowing the stop G to pass by the pin H and the operation can be repeated. The heading or margin at the top and bottom of the sheet to be printed on can be quickly and readily varied by adjusting the gage P and the are D of the cam, which has the stop G attached to it. i

We are aware that reproducing or copying from prepared paper or other material is not broadly new, but it is believed that by adapting the reproducing material to be rotated and locating the inking device within the same, so thattheinkis applied only to theinner periphcry of the prepared paper, we attain the quickest possible manipulation of the same for performing the function for which it is intended, whereby we are enabled to make duplicate copies much more rapidly than heretofore, and at the same time copies can be made on a continuous sheet, which may be fed into the press from a roll suitably supported adjacent thereto.
